The Army Is Shooting Battery Prototypes to Make Sure They Don't Catch Fire... Question for others. Are there other displays that can meet these specs and also accommodate Picture in Picture?

Always looking for lower SWAP (Size, Weight and Power). In this case lower power for IVAS.

Versions of these CWBs will be used in the third Soldier Touchpoint evaluation of IVAS scheduled for July 2020. The high-tech IVAS glasses are designed to equip close-combat soldiers with a head-up display allowing them to view tactical maps, as well as their weapon-sight reticle. Army modernization officials hope to field IVAS in 2021.
